Labour Crisis: 50 MPs Challenge Decision to Block Burnham

Around 50 Labour MPs have written to Sir Keir Starmer urging the party to rethink its decision to block Andy Burnham from standing in the Gorton and Denton parliamentary by election, warning it risks handing a major advantage to Reform UK.

50 MPs Challenge

The letter, also addressed to Home Secretary Shabana Mahmood in her role as chair of Labour’s National Executive Committee (NEC), and to party general secretary Hollie Ridley, says the ruling has caused “huge anxiety and anger” across the Parliamentary Labour Party and among grassroots members.

Signatories argue that preventing Burnham from running is a “real gift” to Reform UK, adding that polling suggests the Greater Manchester mayor may be Labour’s strongest possible candidate in what is shaping up to be a highly competitive contest.

The NEC voted on Sunday morning to deny Burnham permission to stand. As a directly elected mayor, he was required under party rules to seek approval before entering the race. The reported vote was 8 to 1 in favour of blocking his candidacy.

Leadership defends call on resources

Sir Keir has defended the decision, saying allowing Burnham to run would have triggered two elections, a parliamentary by election and a separate mayoral by election across Greater Manchester, placing a heavy strain on party finances and campaign capacity.

“Resources, whether money or people, need to be focused on the elections we must have, not elections we do not have to have,” the prime minister said. “That was the basis of the NEC decision.”

Labour sources say the combined cost of a mayoral by election could exceed £4m and divert staff and funds away from key battlegrounds ahead of major contests in Wales, Scotland and local councils across England.

Supporters of the NEC’s decision argue that combined authority mayors are elected to deliver long term executive leadership, not to treat the role as a temporary platform before returning to Westminster. They also point to the political risk of opening up the Greater Manchester mayoralty mid term, at a time when Reform UK is explicitly targeting low turnout, anti establishment elections.

MPs warn of electoral danger

Those opposing the decision see it very differently. In their letter, MPs say there is “no legitimate reason” to prevent Burnham from standing and call on the NEC to re evaluate its ruling.

One senior Labour source said blocking Burnham had “made an already difficult by election much harder”, adding that many MPs believe his popularity across Greater Manchester could have helped Labour hold the seat.

Burnham has been widely viewed as a potential future leadership challenger to Sir Keir, but he would need to return to Parliament to mount a bid. That political context has fuelled claims from critics that the decision was as much about internal party management as electoral strategy.

Burnham himself said he was disappointed by the outcome and criticised the way the decision was communicated, noting that media outlets were briefed before he was informed. Writing on X, he said he would now return his “full focus” to his role as mayor.

Reform and Greens circle seat

The Gorton and Denton by election was triggered after Labour MP Andrew Gwynne stepped down on health grounds. Labour won the seat in 2024 with a majority of more than 13,000 votes, but the political landscape has shifted sharply since then.

At the last general election, Reform UK finished second with just over 14 percent of the vote, while the Green Party came third on around 13 percent. Both parties believe they have a realistic chance of winning next month.

Nigel Farage has described the contest as an opportunity for an “anti Starmer vote”, arguing that without Burnham on the ballot, disaffected Labour supporters are more likely to back Reform.

The Greens are also expected to mount a strong challenge, with party figures saying they are “throwing the kitchen sink” at the campaign.

Pressure to move on

Despite the internal revolt, senior Labour figures are urging colleagues to close ranks. Former cabinet minister Harriet Harman said MPs should stop relitigating the NEC decision and concentrate on winning the seat.

The by election is expected to take place later this month. With Reform UK and the Greens both sensing an opening, Labour now faces the task of selecting a new candidate and unifying the party quickly, as one of the first major electoral tests of Sir Keir Starmer’s leadership enters a critical phase.
